“nfc”

I'm developing an NFC based app where I've been facing issues such that 'Tag Connection Lost' or 'Tag no response' errors are returned by the 'SendMiFareCommand()' function very frequently. This is observed more frequently on iPhone 12 and above when 5G network signal is weak. Anyway, that's a different issue which I'm following up separately. Because of those frequent errors, I require to Invalidate() NFC session and restart a new session because those errors are non-recoverable. For this purpose, I invoke 'InvalidateSession()', check for session.IsReady flag to be 'false' and then start a new session for the retry. Right after calling 'BeginSession()' at this moment, 'DidInvalidate()' gets hit with an NSError code 'System Resource Unavailable'. What could be the cause behind? I'm checking if previous session was properly invalidated.

In my full application I have a universal link configured on an NFC tag that allows me to launch my application via NFC background tag reading and process additional NDEF records held on the tag via the NFCNDEFMessage provided to onContinueUserActivity(). I can use this same NFC tag to launch my App Clip via the same URL when the full app is not installed. However, unlike the full app the App Clip only receives a single NDEF record with .typeNameFormat = .empty. Is this a limitation of App Clip invocations? I have also implemented full NFC reader functionality within the App Clip which does retrieve all the records from the tag, but of course requires the user to tap the same tag twice to read its full contents. Ideally I would like to avoid requiring users to tap the tag twice to read.

Hello, I have created a digital card on Apple Wallet. How do I give it NFC capabilities without having to apply to Apple? Any workarounds?

Hi, I am trying to create NFC passes in Wallet. The ones I made seems to follow ISO14443-4 but the reader that I want to use only supports ISO14443-3a. It is possible for the passes to be compatible with it? If not, where can I find a list of readers that are compatible with Wallet passes?

Hi I am developing an iOS app where I want the iPhone to act as an NFC tag from where the NFC reader can obtain the users information which is stored on the tag (Like an access card). Does the new iOS support HCE? How can I achieve this?

I have a React-Native application and I implemented a 3rd party eID NFC Reader SDK. This 3rd SDK is using NFCPassportReader library and CoreNFC package also. I'm trying to read Turkish Citizenship eID with this module. My problem this module is working properly in debug mode but It's crushing in release version. I've added a crush log related to this issue and I've added tagReaderSession implementation code. I've added my com.apple.developer.nfc.readersession.iso7816.select-identifiers configuration code also. Does anybody have an idea about that problem?

Hi, We are trying to develop a smart way to share business cards through NFC technology and we already implemented it in android using the HCE sdk they offer however I believe in IOS that is not possible, therefore we are looking for a way to add those business cards on the IOS wallet is that possible?

I have created a Local Experience with an App Clip Card on on two developer devices. While on the iPhone X with iOS 15.7 the chosen photo appears on the App Clip Card, the photo does not appear on the iPhone 12 Pro with iOS 16.2 (it did not with iOS 16.0 before either). Apart from that all content is displayed. What is even more strange: the photo is removed after a while from the App Clip card settings. I tried restarting, different photos to no avail. Any idea? Side note: I have the impression that NFC tag detection is worse with iOS 16.2 compared to iOS 16.0

I have been testing out NFC Tags and I can get some functions to work without having to use the shortcuts app as most NFC's should so they can be used by relatively all users. I cannot get my iPhone 13 to read an NFC Tag with Wi-Fi information, I know the info is written as I can read it from the apps I am writing to them with but it will not read the information. Does Apple not support this? if so why not? You can do it from a QR code but not an NFC?
